ARTHUR BATES, 0F LEICESTER, ENGLAND, ASSIG-NOR TO UNITED SHOE MACHINERYCOMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

LASTING-MAGHINE.

To all whom it may concern Be it known that I, ARTHUR BATES, a subjectof the King of England, residing at Leicester, in the county ofLeicester, England, have invented certain Improvements inLasting-Machines, of which the following description, in connection withthe accompanying drawings, is a specification, like reference characterson the drawings indicating like parts in the several figures.

This invention relates to lasting machines and this application is adivision of my pending application Serial No. 614,154, filed March 13,1911.. The invention is particularly adapted for use in connection withlasting machines of the type described in United States Letters Patent-No. 584,74A, dated June 15, 1897. Machines of the type referred to andcommercially known as hand method lasting machines employ a pair oflasting pincers, which at certain times during the lasting operation aregiven a p-laiting action to crimp or plait the upper at certain parts inorder to dispose of the fullness of the upper materials and so to lastthe upper without wrinkling or puckering. This is especially necessaryat the too where the upper stands out from the last angularly thereto.Commonly, this plaiting action comprises both lateral and turning ortwisting movements of the pincers, the pincers thereby being operated inthe most efficient manner to plait the pulled over margin of upper andlining with absolute smoothness. For imparting the above describedplaiting movements to the lasting pincers, cam actuated mechanism isprovided. This pincer plaiting mechanism is normally inoperative and acontrolling clevice, commonly a block mounted to slide in a segmentalguideway, serves both to start and suspend the action of the pincerplaiting mechanism and also to determine, control and vary the extent ormagnitude of the plaiting action. To this end, the block or controllingdevice is normally mounted centrally and midway of the guideway and theguideway which carries the block is formed on a lever or driver which isrocked continuously by a rock shaft actuated from a cam on the mainshaft, the construction being such that whenever the block orcontrolling device is displaced from its central Specification. ofLetters Patent.

Original application filed March 13, 1911, Serial No. 614,154. Dividedand this application fi1ed June 8, Serial No. 631,938.

and inoperative position, the pincers are actuated through suitableconnections with the controlling device to plait the upper and wheneverthe controlling device is returned to its neutral position, the pincerplaiting action is stopped or suspended. The controlling device, assuggested above, also serves to control and vary the direction andextent of plaiting action and, to accomplish this result, it is adaptedfor movement either side of its central position, the direction andamount of its displacement from central position governin the directionand amplitude of the planting action of the pincers.

In order that the plaiiing action may be initiated, controlled andvaried at will, it is usual to provide a knee lever movable either sideof its normal position and suitably connected with the block whichcontrols the plaiting action, whereby the plaiting action can beeffected and changed in direction and extent as desired by movement ofthe knee lever one way or the other. In the practical use of the machineof the said prior Letters Patent, however, the shoe is manually held upto the pincers and the direction and extent of its feed past the pincersis controlled by the hands of the operator. Since both the direction ofthe plaiting and the extent or magnitude thereof should for the bestresults depend upon the extent and direction of the feed and should atall times be made to correspond therewith, to relieve the operator ofthe necessity of attending both to the feeding of the shoe past thepincers, and to the regulating of the pincer plaiting action incorrespondence therewith is a principal object of this invention. Withthis object in view, broadly speaking, the presentinvention contemplatesmaking these two actions automatically interdependent and, to this end,preferably, and as shown and hereinafter described in detail, theconstruction is such that the operator may by feeding the work therebycause the plaiting action to occur in timed relation with andcorrespondingly in direction and extent to the feeding action.

Accordingly a preferred embodiment of this invention comprises provisionin a lasting machine of the type above mentioned, of means whereby thefeed of the work controls the plaiting mechanism and convenmechanism insuch a manner that the actuation of the work engaging means by the feedof the Work will simultaneously initiate the plaiting action and so thatthereafter any variation in the direction and extent of the feed will atthe same time cause the direction and magnitude of the plaiting actionto be similarly varied.

Considered more in detail the invention as preferably embodied in themachine of the said prior Letters Patent comprises a rotatable wheel orwork engaging member adapted to engage the bottom of the inverted shoeand operative connections between this wheel and the movable controllingdevice hereinbefore referred to.

T In the illustrated form of the invention the manual feed of the Workagainst the wheel rotates the wheel in one direction or another so thatthe wheel and its associated parts, together with the movable blockconstitute means for rendering the plaiting mechanism operative and therotation of the wheel through the connections between the wheel and themovable block operates to set the block controlling device for governingthe action of the plaiting mechanism.

This invention will now be described, as applied to a lasting machine ofthe type illustrated in the specification of the above mentioned LettersPatent, but it is to be understood that this is merely by way of eX-ample, and not by way of limitation, for the invention in its broadaspect is not limited to use in this particular type of machine, nor isit limited to embodiment in the precise form illustrated and described.As above stated the present invention is shown as embodied in themachine of the said prior United States Letters Patent and referenceshould be had to the specification thereof for matters of constructionand for details ofdescription not fully'entered into herein. Forconvenience, parts herein shown which are like, or similar to parts inthe specification of the said prior patent are generally indicated bylike reference characters.

Referring to the drawings :Figure 1 is an angular perspective inelevation of a part of the machine of the specification of the beforementioned Letters Patent with one embodiment of the present inventionapplied thereto; Fig. 2 is an elevation of the work engaging member andassociated parts; and Fig. 3 is a detail in elevation of the workengaging member and associated parts partly in section as looked at fromline 3-3 of Fig. 2.

The operating mechanism of the machine is supported in a frame work orhead 13 mounted at the top end of a supporting column. J ournaled in thehead B is a shaft D, this shaft being the main driving shaft of themachine and having set upon it the cams and gears from which theprincipal operating parts of the machine receive their auto-' maticmovements. On the shaft D is a cam 280 connected by a slide E with atipping updraw lever 18 fulcrumed at 19 and having the pincers suspendedby a ball X from its front end. The pincers comprise a stationary aw 14fixed in the pincers carrier and a movable jaw 16. The pincers carriercom-' prises a casing or sleeve 13 through which extends a rod 15 havingpivotally connected to itthe movable jaw 16 and operating to close theaw 16 for gripping the stock; the jaw 16 being reversely moved by thespring S. The rod 15 is engaged by a spring pressed plunger 27 on onearm of a rock shaft 36, the other arm of which has a roll in engagementwith an edge cam face 40 on shaft D, whereby upon the revolution ofshaft D and cam 40 at suitable times the pincers are caused to be closedand opened for gripping and releasing the upper. Besides the opening andclosing movements of the pincers thus effected, the pincer mechanism asa whole is at certain times raised and lowered through tipping movementsof lever 18 induced by upward and downward movements of slide E actuatedby cam 280 on shaft D, the upward movement of the pincer mechanismoccurring after the pincers have tightly gripped the upper and servingto strain the upper vertically, while the ensuing downward movement ofthe pincers lowers them into position for placing the ;upper over theinner sole.

plaiting movements consisting of lateral and turning movements by meansof which the upper is folded, particularly at the toe of ithe shoe, totake care of the surplus in the ;margin of the upper which is laid overthe curved edge of the last. The turning movements of the pincers areeffected through a .link 1 8 connected to a lever X, the upper lend ofwhich is connected to a rack X which jengages teeth formed on the ball Xfor ro- Qtating the pincers. jmovements of the pincers, the pincers arearranged to extend downwardly through a guideway formed in an endwisemovable block 51 which is supported in the forward ;end of a yoke on asliding rod 50. Movejment of the sliding block 51 is effected through arod 55, the construction being :such that movements of block 51 one wayand then the other will operate through suitable connections, clearlyshown and de To effect the lateral their vertical line of action. Foroverlaying.

=upward and downward and overdraw movements of the pmcers, the pmcersare given ,plaltlng movements at certain times, the

the upper when the pincers have, through downward movement of theforward end of lever 18, been placed in their lowermost position asbefore stated, the sliding rod 50 has a roll for engaging a cam 4L1 onthe shaft D to move the pincers toward the machine, and the rear end ofrod 50 is engaged by a lever 54 actuated by a spring 53 for moving thepincers from the machine to overlay the upper.

The above described means for turning the pincers and for moving themlaterally are actuated from the cam 61 through a lever 60 supported by apin 302, the inner end of the lever 60 having a roll standing in the camgroove 61 and the outer end operating to actuate a rock shaft 56.

The parts above described may, as shown, be substantially the same inconstruction and operation as the similar parts of the machine of saidprior patent, and further detailed description thereof will therefore beomitted. In the machine of said patent, the above mentioned rock shaft56 carries on its front end a rocker which, for convenience. may betermed the driver for the pincers plaiting mechanism, and which forms asegmental guideway for a segment block formed to slide in the saidguideway and movable therein from and toward the center of the rocker.The said segment block has connections both with the lever X and withthe rod 55, and upon adjustment operates through the said lever and rodthe above described means for turning the pincers and for moving themlaterally. The construction is such that the pincer plaiting mechanismis normally inoperative but is adapted to be thrown into operation uponadjustment of the said block from its central or neutral position in thesegmental guideway, adjustment of the block one side of its normalposition directing the plaiting action one way and adjustment of theblock the other side of the central position directing the plaitingaction reversely, while the amount of plaiting action is in eachinstance controlled by the amount of movement of the block from itsinitial position. The segment block thus operates as a controllingdevice to start and stop the lateral and turning movements of thepincers as well as to govern and vary the direction and extent of thesaid pincers movements.

The illustrated construction by which, in accordance with the presentinvention, the pincer plaiting movements may be made to correspond withthe feed of the work may be described as follows:-As in the machine ofthe said patent, the pincer plaiting mechanism is normally inoperativeand is adapted to be actuated upon movement of a movable block. Themeans for actuating and controlling the direction and extent of movementof that block according to this invention comprises the rotary workengaging wheel 80 and its connections with the said block. The wheel 80is rotatably carried at the lower end of an arm 82 fixed to the frame ofthe machine projecting i11- wardly toward the pincers, and has itsoperating face toothed or corrugated for engaging the work withoutslipping. At its center is a projecting point 84 adapted to engage theinsole at the toe portion so that the working face of the wheel may bemaintained in proper position with relation to the sole to effect thefeeding of the work. Journaled inside the projecting arm 82 is a shaft86 (Fig. 3) having a bevel gear con nection at its outer end with thewheel 80, and being connected at its other end by bevel gears to anupright shaft 88. The shaft 88 has loosely mounted upon it a cam 90(Fig. 3) having a spiral groove. The lower edge of the cam 90 is formedwith teeth 92 which are adapted to engage similar teeth upon a collar 91fixed to the shaft 88, and are normally forced into engagement withthose teeth by means of a spring 90 so that cam 90 is normally clutchedto shaft 88. Pivoted upon the frame of the machine at 98 (Fig. 2) is alever 100 carrying at its outer end a cam roll 102 engaged by the spiralgroove in the cam 90, and at its opposite and inner end the lever 100 isprovided with jaws 104 which are adapted to engage a block 106 which isin all respects the equivalent of the before mentioned block controllingdevice of the machine of the said patent. The block 106 has pivoted toit a link 108, the other end of the link 108 being pivoted upon an arm110 projecting from the rock shaft 56 which in the machine of the saidprior patent carried the segmental guideway, the link 108 forming withthe arm 110 what may conveniently be termed an inverted toggle. Thisblock 106 is also connected through rod 55 and link X to the plaitingmechanism and constitutes a sensitive and readily shiftable connectionbetween the rest and the plaiting mechanism.

In operation the operator feeds the shoe past the pincers by hand, as inoperating a machine of the said prior patent and the feed of the workbearing against the wheel 80 causes said wheel to be rotated, and therotation of wheel 80 through shafts 80 and 88 causes cam 90 to berevolved. The revolution of cam 90 operates the roll 102 lying in thespiral groove of cam 90 to rock the outer end of lever 100 up or down.The opposite movement being given to the jaws carrying end of lever 100,the block 106 is moved up or down as the case may be. WVhen in centralposition the center of block 100 coincides with the center of the rockshaft 56 and, therefore, motion of the rock shaft imparts no motion tothe plaiting pincers. When, however, block "124 is moved up or down fromits neutral position its center no longer coincides with the center ofrock shaft 56, and consequently when rock shaft 56 moves, its projectingarm 110 and the link 108 also move and, as the block 106 is connected tothe plaiting mechanism through the link X and rod 55, that mechanism isoperated as in the machine of the said prior patent to impart plaitingmovements to the pincers. It will be apparent that by reason of thisconstruction the initiation, direction and extent of the feed of thework will determine and govern in correspondence therewith the starting,stopping, direction and magnitude of the plaiting ac tion. In order thatafter each plaiting operation and while the pincers are being returnedinto position for another operation the spiral cam 90 may also bereturned to normal position, a cam roll 112 (Fig. 3) is provided on ashort arm depending from the pincer casing 13 and this roll 112 on thebackward and return movement of the pincers is brought into engagementwith one end of a bifurcated lever 114C pivoted at 116 to the arm 82,the construction being such that when thus operated the bifurcations oflever 114 by reason of ribs upon them engage and lift the toothed cam 90from engagement with the teeth on the collar 94 of the shaft 88, and atthe same time a flat face 118 projecting from the upper end of the lever114 abuts against a correspondingly shaped face upon the spiral cam 90and operates to turn cam 90 to restore it to its mid-position. The lever114: is provided at one end with a spring pressed plunger 120, the saidplunger operating, when permitted, to withdraw the face 118 fromengagement with the cam 90 to permit the cam 90 to be again operatedafter having been restored to its initial position.
